3 Claims.

This invention relates to a combination allpurpose door adapted for usegenerally in buildings for outside doors and especially intended andadapted for use with doors of homes which open to the outside orexteriorly of the enclosure.

More particularly, the primary object of the present invention is toprovide a combination door which will eliminate the need for a separatescreen door and storm door and in which will be incorporated theadvantages of both types of doors in addition to a conventional door.

Another object of the invention is to provide an improved constructionof door capable of being quickly and easily converted from a combinationdoor and storm door to a combination door and screen door and which willeliminate the need for separate screen and storm doors.

Still a further object of the invention is to provide a combination doorwhich will be more durable than conventional screen doors, the screen ofwhich will not be damaged by young children pushing thereagainst, andwhich will prevent dust and dirt from being blown through the door,through the lower part thereof.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawing, illustrating the preferred embodiment thereof, and wherein:

Figure 1 is a side elevational View on a rela tively reduced scale of apreferred embodiment of the invention looking toward the outer sidethereof and showing the screen incorporated with the door;

Figure 2 is an enlarged longitudinal sectional view taken substantiallyalong a plane as indicated by the line 2-2 of Figure 1 and showing thetransparent pane of the door in a retracted, open position;

Figure 3 is an enlarged horizontal sectional View taken substantiallyalong a plane as indicated by the line 3 3 of Figure 1;

Figure 4 is a vertical sectional View taken substantially along a planeas indicated by the line 4-4 of Figure 2 and showing the transparentpane in a partially raised position; and

Figure 5 is a fragmentary vertical sectional View taken substantially onthe same plane as Figure 2 and showing the door with a storm windowsubstituted for the screen window thereof.

Referring more specifically to the drawing, S designates generally theimproved door in its entirety and which comprises the invention. rlhedoor in Figures 1, 2, and 3 is illustrated disposed in a frame Idefining a door opening and swingably supported along one edge thereofto a stile of the frame 1 by means of conventional leaf hinges 8. Thedoor 6 is provided adjacent its opposite longitudinal edge andpreferably slightly below the mid-point of the top and bottom thereofwith a conventional door knob 9. It will be understood that the door 6is provided with a knob 9 on each side thereof and that said knobs areconnected to and operate a latch means, not shown, for engaging a keeperin the other stile of the door frame 'I and that a suitable lock, notshown, may also be provided for locking the latch means.

The door 6 comprises an inner, relatively thick panel I I) and an outer,thinner panel II which is preferably secured to the outer side of theinner panel I0 by countersunk screw fastenings I2. The upper portion ofthe door E5 is provided with a relatively large opening I3, formed inthe panels I0 and II and the outer side of the panel I0, around the topand sides of said opening I3 is reduced in thickness and the space,thereby afforded, is filled by a removable filling strip I4 which isdetachably secured between the recessed part of the outer side o-f thepanel I0 and the panel II by certain of the fastenings I2.

The panel IIJ is provided with a relatively deep well I5 which opens atits upper end into the bottom of the opening I3. The portion of thepanel I 0, defining the opening I3 is also provided with downwardly andinwardly opening channels IB, the outer sides of which are defined bythelling strip I4. The vertically extending inwardly opening channels I 6also form continuations of the 4edge portions of the well I5. Thechannels I6, and the edge portions and bottom of the well I5 are linedwith felt or similar material Il.

As best seen in Figure 4, the top rail portion of the inner door panel I0, adjacent the upper corners thereof, is provided with correspondingoutwardly opening recessed portions l having restricted passages I9communicating with the ends of the upper, downwardly opening horizontalchannel I 6. A roller 20 is journaled in each of the recesses IB on apin 2l and a tape 22 is wound on each roller 20 and extends downwardlytherefrom through the associated opening or passage I9 and into thevertical groove or channel IB which is located directly beneath.

A pane of glass or other transparent material 23 is sized to t, when ina retracted position, substantially within the well I5 and with theupper edge portion thereof protruding slightly into the lower part ofthe opening I3 and with the side edges of said portion disposed in theinwardly opening side channels I 6. The lower, free ends of the tapes 22are secured to the side edges oi the pane 23 by pins or other suitableanchoring means 24. A spring 25 is interposed between each roller 20 andits pin 2|; said springs being anchored at one end to the pins and atthe opposite ends thereof to the rollers causing said rollers to berevolved in a direction for urging free ends of the tapes 22 upwardlytoward the recesses I8. It will be readily apparent that the i outwardlyopening recesses I8 will be exposed by removal of the panel II and thefilling strip I4 to afford access to the rollers 23.`

An open frame 26 is detachably mounted in the portion of the opening I 3formed by the-panel I I; said frame 26 being sized to t relatively tightin said opening and being swingably supported therein by means of leafhinges 2'I at the top of the frame 26 and in the upper part of theopening- I3. The frame 26 is provided with an opening 28 across which astrip of mesh wire fabric 29 is stretched. The frame 26'is providedwith. a removable outer section 30 surrounding the opening 23 thereofand between which and the remainder of the frame 2B, the edge portion ofthe wire fabric is clamped. The removable frame portion 30 may besecured in position in any suitable manner and is intended to be removedonly for replacement of the screen 29, ifisuchv should be required. Aspring, latch member'- 31 is suitably anchored at one end thereofbetween the panels I and I I and projects therefrom into the lower partof the opening I3 and is adapted to engage over the bottom rail of theframe 26, inwardly of the wire fabric 29, for detachably retaining saidframe in its normal, closed position of Figure 2.

As illustrated in dotted; lines in Figure 4, the inner side of thepane23 is provided-with recessed portions adjacent the upper edgethereof forming nger holds 32 which are disposed slightly above thebottom oi the opening I3 when the pane 23 is in a retracted position inthe Well I5, as illustrated in Figure 2. A grip may be obtained on thepane 23 by mea-ns of the nger hold 32 for raising the pane 23 fromits-fully-retracted position, of Figure 2 to a partially raised andclosed position, as seen in Figure 4*. ori to a fully raised and closedposition, as seen in Figure 5. The spring actuated rollers inurging'thetapes 22 toward a wound positionV thereon will assist in raising thepane 23 by substantially counterbalancing the weight thereofand areofsufficient strength to retain the pane 23` in either a partially orfully raised, and closed position. The felt linings of the channels Iand the well I5 will also function tofrictionally retain the pane 23 inany position to whichv it is manually moved and will cushion said paneto preventl damage thereto resulting from slamming of the door 6 andalso function as weather stripping to prevent the passage of air betweenthe pane 23 and opening I3when the formerfis ina fully raised and closedposition, as seen in Figure 5.

Figure 5 is a fragmentarysectional view illus- 6 trating the door 6'employed as a storm door and for use during cold weather. A stormwindow, designated generally 33 and comprising a frame 4 34 having anopening 35 and an inwardly opening channel 36, which opens into theopening 35 is shown mounted in the opening I3 and in place of the screen26, 29. A glass pane 31 or a pane of other transparent material has itsmarginal edge portions seated in the channel 36 and closes the opening350i said frame 34. The upper rail of the frame 34 is swingably securedin the upper part of the opening I3 by hinges 38 in the same 2 mannerand for the same purpose as the hinges 2'I, and it will be readilyobvious that the same hinge leaves which are secured to the panel II maybe utilized for mounting either the window screen or storm window bymerely removing the hinge pins and interchanging the screen or stormwindow. It will be readily seen that either of said closures may beselectively mounted in the opening I3 for providing either a storm doorwith the pane 23 raised and the window 33 utilized or a screen door withthe pane 23 retracted and the screen closurel 26, 29 employed. The panes23 andV 3l' of the storm door will provide an air chamber therebetweenwhich will effectively function to reduce the amount of heat or coldwhich would otherwise be conducted through the pane 23. The storm frame35 may be lined with felt or other weatherstripping 39 to preventpassage of air between the frame and opening I3.

Various modifications and changes are contemplated and may obviously beresorted to, without departing from the spirit and scope of theinvention as hereinafter dened by the appended claims.

I claim:

1. A combination door comprising an inner panel and an outer panel,means for detachably connecting said panels together, said door beingprovided with an opening inthe upper part thereof, said inner panelbeing provided with a well in the lower portion thereof and openingupwardly into said opening, a transparent pane for normally closing saidopening, said pane being retractable into said well, and a window frameswingably and detachably mounted in said outer panel and closing theopening thereof.

2. A door as in claim l, and a sheet of mesh wire fabric engaged in saidframe and combining therewith to form a screen window.

3. A door as in claim l, and a pane of transparent material closing theopening of said window frame and combining therewith to form a stormwindow and combining with the pane of said door, when in a raised andclosed position, to form an air chamber within the door opening.
